Columbia River Crossing Owner’s Engineer (CRC)

Location: Oregon and Washington

The purpose of the Columbia River Crossing project is to improve the mobility, reliability, and accessibility for automobile, freight, transit, bicycle, and pedestrian users of the I-5 corridor connecting the states of Oregon and Washington.

The 90-year-old I-5 bridge is a major lifeline for the communities, currently carrying more than 130,000 crossings daily and carrying the freight and commuters that support the economy and vitality of the region and the entire West Coast. The bridge has been stretched far beyond capacity. The hours of stop-and-go traffic grow every year. Anticipated growth will only make congestion worse, causing longer and longer delays.

DEA is leading a 20-firm team of national experts in the preparation of an environmental impact statement for the evaluation of Columbia River crossing alternatives for I-5 between Portland, Oregon, and Vancouver, Washington.

The team is evaluating alternatives to replace the existing bridge and to provide a four-mile section of I-5 with additional multimodal capacity, including opportunities for transit, freight, auto, bike/ped, air, and marine.

DEA is also leading the development of the sustainability plan for the project. The plan considers energy, hydrology, carbon, materials, human and natural resources, and complete life cycle costs of the project.

The project team is sponsored by eight agencies, including two state departments of transportation, two metropolitan planning organizations, two public transportation agencies, and two cities.

DEA has been a part of the Columbia River Crossing project since the first phase corridor study in 1999 to define the transportation problems in the busy metropolitan, interstate corridor to determine whether there were solutions that merited further investigation, and to recommend an action plan for moving forward. DEA services provided over the years have included project management; transportation planning; traffic engineering; highway, bridge, and transit engineering; and environmental studies.
